Electrodes fired
Hi
There was a theory that there was a one-to-one correspondence between the image the eye sees and the way that image is represented in the brain. In other words when we look at a square it was believed the electrical activity in our visual cortex also possesses the form of a square.
However one guy wanted to find out whether this is true or not. He spent some time measuring the electrical activity in the brains of monkeys while they performed various visual tasks. He discovered that not only did no such one-to-one correspondence exist, but there wasn't even a discernable pattern to the sequence in which the electrodes fired.
--- Now I'm wondering whether "electrodes fired" means that the electrodes got activated when they received the signal from the brain or maybe they sent some signals to the brain and that's why it says "fired"? In my opinion "fired" means they received signals from the brain, they got activated.

Mister Micawber They sent images to the brain.Well, that means I didn't understand much from the above passage, but thanks for the answer.

I'm almost certain that you were correct and Mr. Micawber was mistaken in this case, since the passage specifically talks about the experimenter measuring brain activity as monkeys looked at things, not about the experimenter stimulating the brain with electrodes and then somehow trying to determine what the monkey was seeing. If you think about the actual experiment, it wouldn't make any

CSnydernot about the experimenter stimulating the brain with electrodesThat's why I thought that 'electrodes' was a misnomer for synapses—but you may well be right, CS. I don't have great confidence in my interpretation.
